Sharp bounds for japþ2 lapþ1j and jap+3j are derived for certain p-valent analytic functions. These are applied to obtain Fekete-Szegö like inequalities for several classes of functions defined by… (More)

In this paper, for the integral operator { β ∫ z 0 ξβ−1 ∏n i=1 ( fi(ξ) ξ ) 1 α dξ }1 ξ to be univalent in the open unit disk, conditions on β,α and fi(z) are determined. Let A be the class of all… (More)

In this paper, we determined conditions on β, αi and fi(z) so that the integral operator { β ∫ z 0 tβ−1 n ∏ i=1 ( fi(t) t ) 1 αi dt } 1 β is univalent in the open unit disk for the two subclasses… (More)

Using the methods of differential subordination and superordination, sufficient conditions are determined on the Liu-Srivastava linear operator of meromorphic functions in the punctured unit disk to… (More)

Let the functions q1 be analytic and let q2 be analytic univalent in the unit disk. Using the methods of differential subordination and superordination, sufficient conditions involving the Schwarzian… (More)

Let A,B,D,E ∈ [−1,1] and let p(z) be an analytic function defined on the open unit disk, p(0) = 1. Conditions on A, B, D, and E are determined so that 1 + βzp′(z) being subordinated to (1 +Dz)/(1… (More)

In this paper, we introduce the concepts of intuitionistic fuzzy πgα closed mappings and intuitionistic fuzzy i-πgα closed mappings. Further, we study some of their properties. MSC: 54A40, 03F55.

In the present investigation, we obtain some subordination and superordination results involving Dziok-Srivastava linear operator H l m[α1] for certain normalized analytic functions in the open unit… (More)
